WHEEL=PLOW.

SPECIFICATION forming' part of Letters Patent No. 718,705, dated January 20, 1903.

Application filed June 28,1902- Serial No. 113,588. (No model.)

To all whom t may concern.-

Beit knownthat I, CHARLES T. ELLisToN,

a citizen of the United States, residing at (llin- The object of the invention is to provide a,

plow of this class which can be quickly and easily regulated to any depth desired, one which is attached to a beam which is pivoted at its forward end, and one in which the entire weight of the plow is suspended by means of an adjustable chain or cable connected to the rear portion of the frame members.

Another object of the invention is to provide a skeleton frame, to which the frame members are connected; and another object is to provide a pivot-frame within the skeleton frame and to which the plow-beam is pivotally connected, the said arrangement of skeleton and pivot frame permitting the plow to make very short turns.

Another object is to provide a skeleton frame with adjustable axles carrying the ground-wheels and by means of which the frame or carriage can be adjusted to travel in a level position upon any and all conditions of ground.

Another object of the invention is to provide an adjustable colter carried by the plowframe in advance of the plow and entirely independent thereof.

With these objects in View and certain others, as will appear hereinafter, the invention consists in the various features of construction, combination, and arrangement, all of which will be fully set forth in the description and specified in the appended claims.

In the drawings forming part of this speciication, Figure l is a perspective view of a wheel-plow constructed in accordance with my invention, the plow being shown in its raised or elevated position. Fig. 2 is a detail perspective view of the skeleton frame. Fig. 3 is a view of the pivoted frame. Fig. I is a detail perspective view showing the manner of connecting the forward end of the plowbeams to the pivoted frame. Fig. 5 is a top plan view, the plow being shown in its lowered or working position. Fig. 6 is a longitudinal sectional view showing the plow in its lowered or working position. Fig. 7 is a detail sectional View on the line 7 '7 of Fig. 6. Fig. Sis a detail sectional View illustrating the manner of adjusting the forward end of the plow-standard.

In the construction of a plow in accordance with my invention I provide a skeleton frame A, which is composed of an upper arched section A', having lateral extensions A2, and the lower drop-section A2, also having lateral extensions A2, the upper and lower sections of the frame being united by means of the perforated plates A4, and the outer ends of the lateral extensions A2 are connected to the plates A5, the rear upper edges of said plates A5 being curved in the arc of a circle and provided with rack-teeth A6. The axles B are pivotally connected to the skeleton frame, the

horizontal portions B' being journaled in the perforated plates A4 and A5, said axles being carried downwardly, as shown at B2, said de pending portions terminating in short sections B2, upon which the ground-wheelsBare mounted. Hand-levers B5 are rigidly connected to the upper sections B adjacent to the plates A5, said hand-levers being provided with spring-latches B6, which are adapted to engage the rack-segments A6. By means of this construction the skeleton frame can be raised or lowered as desired by raising and lowering the hand-levers, and inasmuch as the axles are independent of each other it is obvious that one wheel can be raised and the opposite wheel lowered, if so desired, thereby accommodating all conditions of ground, and thus enabling the plow to be moved in a level position for hillsides or steep grades.

An essentially rectangular frame O is pivotally mounted within the skeleton frame A, between the upper and lower sections thereof, said frame O being pivoted by means of bolts or rivets O', passing through the upper and lower members of the said frame C and also IOO each other and beyond that point are continued in parallel relation and at their rear ends are united by means of a coupling-block D2, in which is journaled the shank of the bracket carrying the caster-wheel D1. The seat-bar D5 is also rigidly connected to the rear ends of the members of the frame D and projects forwardly in order to support the seat in the proper position. The plow-beam E is arranged between the members of the frame D, the forward end of the beam projecting through the pivoted frame C, andthe said forward end is pivotally connected to the sides of said frame through the medium of links E and E2, the link E' having a lever E2 extending at right angles therefrom and to which is connected a rod E4, which in turn is pivotally connected to the handlever E5, provided with a spring-latch E6, adapted to engage a toothed segment E2, mounted upon one member of the plow-frame, and it will also be noted that the hand-lever is pivoted to one of the said frame members. The link E' is pivoted direct to the frame C, the links E' E2 being shown in dotted lines in Fig. 6. The construction of the links is shown in Fig. 4, and the connection of the link E to E2 is shown in Fig. S. By means of the hand-lever and the link connections the forward end of the plow-beam can be raised or lowered as desired, and this movement, it will be noted, is entirely independent of the adjustment of the skeleton frame. The plow-beam extends rearwardly between the plow-frame members and is curved downwardly, as shown, at its lower and rear end has the plow F connected thereto, said plow being of the usual or any approved construction. A supporting-chain F' is connected to the plow, preferably at the rearend of the landside, the upperend of said chain being connected to a winding-shaft F2, journaled in the plow-frame D, and having an operating-lever F3 rigidly connected to one end thereof, and this lever F3 is provided with a spring-latch F4, which is adapted to engage the rack-segment F5, carried by a sleeve F6, projecting from one side of one of the plowframe members and through which the extended end of the shaft F2 passes. By operating the hand-lever F3 the shaft is moved to wind or unwind the chain F', thereby raising or lowering the plow, and it will be noted that inasmuch as the plow is rigid with the beam and the said beam pivoted onlyat its forward end a slight movement of the hand-lever will produce a considerable adjustment in the plow. Furthermore, by supporting the plow in the manner set forth it is maintained in a thoroughly level position and the entire force of the draft is exerted upon the frame. A rolling colter G is carried by a bracket G', having a shank G2, adjustably connected to the plow-frame D by a clip G2. This colter can be adjusted to cut into the earth to any desired depth and travels directly in advance of the plow and adjacent thereto, and it will also be noted that the plow and colter are absolutely independent of each other, and each one can therefore be adjusted or moved independent of the other. Suitable foot-rests H are attached to the plow-frame D and project laterally therefrom. A draft-bail I is pivotally connected to ears carried by the lateral extensions A2. By having the plowframe connected to the pivoted frame which is carried by the skeleton frame I am enabled to make short turns, and by having the plowshare adjustable independently of the plowframe I am enabled to maintain the plow in the proper level position at all times. Furthermore, by having the plowshare adjustable from the forward end of the standard a quick and easy adjustment is obtained. A plow constructed as herein shown and described will be exceedingly strong, durable, light, and efficient and will accomplish all of the objects herein mentioned.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
